[Breast cancer screening: modeling improvement of access using mobile mammography unitsSeguimiento del cáncer de mama: modelo de mejora del acceso con el uso de mamógrafos móviles].

Objective: To investigate the impact of combined use of fixed and mobile mammography units to rationalize the management of breast cancer screening programs and increase population coverage.

Methods: An observational study was performed using agents-based modeling. The model was used to simulate breast cancer screening coverage in a specific region in the state of Rio de Janeiro () where 22 fixed mammography units are installed.

[Cost-effectiveness of hepatitis C treatment in slow virologic responders coinfected with HIV].

Recent evidence has demonstrated that slow responders may benefit from antiviral treatment in HCV/HIV coinfection. This study aimed to evaluate the cost-effectiveness of HCV treatment in individuals with genotype 1 coinfected with HIV, with peg-interferon in combination with ribavirin, compared to the inclusion (versus non-inclusion) of slow responders. A Markov model was developed that simulated the progression of liver disease in a hypothetical cohort of one thousand men over 40 years of age, considering the Brazilian Unified National Health System (SUS) perspective and a 30-year timeline.
